To (dice/ 10m it may concern Be it known that I, ALBERT S. lVALLACE, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tire Tools; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had. to the accompany ing drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to tools for removing clincher tires from automobile wheels. The chief difficulty in tire removal is to lift one part of the tire over the adjacent portion of the rim when the rest of the tire may be quickly detached.

It is an object, therefore of the present invention to provide improved means for disengaging one part of the tire from the adjacent portion of the rim.

Another object of the invention is to provide a pair of tire tools, one adapted to disengage one bead and the other adapted to disengage the other bead from the rim of the wheel.

Other and further important objects of this invention will be apparent from the dis closures in the specification and drawings.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

As shown in the drawings:

Two tire tools 1 and 2 are provided for aiding in the removal of the tire. The first of these, 1 is fiat bar provided with a. hook 3 at its end for engagement with the rim of the wheel, as shown in Figures 1 and 2. Adjacent this hook a lateral extension 4. The lever l is aoapted to be hooked upon the rim as shown in Figures 8 and 9. The lever is then raised into horizontal position as shown in dotted line in Figure 9 and is given a lateral swinging movement to bring the same into the position shown in Figure 10; the hook-shaped end 3 serving as an anchor against the tire rim while the projection at in said lateral movement acts against the tire and pushes the same inwardly away from the rim head. The lever 1 is next elevated into the position shown in Figure 11, an operation which raises the tire head from the rim and directs the same inwardly to a considerable extent, forming the passageway thereunder for the next tool.

The second tool is a flat bar having a flattened end 5 which is twisted slightly to aid its insertion beneath the opposite head of the tire. Along one edge of the tool is formed a downwardly and rearwardly projecting hoolz. 6 adapted to engage the rim of the wheel and act as a pivot or fulcrum. its the tire is being held in the posit-ion shown in Figure 1]., the second lever 2 is positioned adjacent the lever 1 in the position shown in Figure 12; the lug 6 upon the inner side of the sheet metal rim serving as a fulcrum. The lever 2 is now shifted laterally and forwardly to bring the same into a. position transversely of the tire and under the bead view of a part of the tools in their final posi- 8 as shown in Figures 13 and 14, in which position, the sheet metal rim will serve as a. fulcrum whereby pressure upon the outer end of said tool will raise the inner end thereof and lift the head 8 of a tire out of the head in the sheet metal rim, allowing thereby the tool 2 to be shifted underneath the head 8 and upon the opposite head of the sheet metal rim as shown in Figure 15, so that the tire is held above the supporting rim. The tool '3. may now be withdrawn and turned end for end, and the beveled handle thereof may be inserted under the tire and supported upon the two heads of the sheet metal rim as shown in Figure 16. Either one of the tools, but preferably the tool 1, may now be forced circuinfereutially around the sheet metal rim, prying the tire therefrom until a s'u'llicient portionof the tire has been'thusvvise pried loose-from the rim so that the tire may be removed by raising up on the levers as is obvious.

I am aware that numerous details of constructlon may be varied through a wide range without departing from the princi- ,i

the end adjacent said lug in the form of a hook for the purpose set forth.

in testimony whereof lhave hereunto subscribed my name in the prcsenceof two subscribing witnesses:
